SUMMARY

The discussion centers on the analogy of the universe functioning as a giant capacitor, which is fundamentally incorrect. Key points include the distinction between energy storage in batteries (chemical energy) and capacitors (electric fields), the finite amount of energy in the universe, and the law of conservation of energy. It is concluded that conservation of energy is a local phenomenon and does not apply on cosmological scales, rendering the analogy invalid.

PREREQUISITES
  • Understanding of electrical energy storage mechanisms, specifically batteries and capacitors.
  • Knowledge of the law of conservation of energy.
  • Familiarity with electromagnetic fields and their role in energy storage.
  • Basic concepts of cosmology and energy distribution in the universe.
NEXT STEPS
  • Research the principles of energy storage in capacitors and batteries.
  • Study the law of conservation of energy in both local and cosmological contexts.
  • Explore the role of electromagnetic fields in the universe.
  • Investigate cosmological models that explain energy distribution on a large scale.
USEFUL FOR

Physicists, electrical engineers, cosmologists, and anyone interested in the fundamental principles of energy storage and conservation in the universe.

[Since "the universe is a capacitor" got zero hits on Google, I'm reasonably sure this is wrong, but I'm just not sure why it's wrong. Thanks in advance for your response.]

Batteries and Capacitors, both store electrical energy.

Energy in a battery is stored in the form of chemical energy, where as energy in capacitor is stored in the form of electric fields.


1) There is a fixed finite amount of energy in the universe.
2) the law of conservation of energy says that energy can neither be created nor destroyed,
3) most of the energy in the universe is stored in the form of EM fields.

Soooo... doesn't it follow that the universe functions like a giant capacitor? Is this correct? Is the universe a giant capacitor?

Conservation of energy is a local phenomena that does not apply on cosmological scales, so the basis for your question is wrong and thus the question has no real answer (although "no" is not a bad answer).
